The American Basketball Association (ABA) was a men’s professional basketball league from 1967 to 1976. The league merged with NBA in 1976, leading to 4 ABA teams joining the NBA. The ABA was instrumental in shaping the current NBA as it lead to the introduction of the 3-point shot in the NBA in 1979.
